The user terminal apparatus includesreception module for receiving the social information transmitted fromthe social information transmission module over the broadcast wave whilethe user terminal apparatus is arranged in any of the broadcast ranges,and presentation module for presenting the social information receivedby the reception module.

An embodiment will be described below with reference to the accompanyingdrawings.

A social information providing system according to the embodimentassumes that social infrastructure information and facility/equipmentinformation are processed as social information. The socialinfrastructure information includes pieces of information from sensorsattached to a mobile vehicle (to be referred to as a power supplyvehicle) capable of supplying power to an electric vehicle, a wattmeter,a power supply station, a thermometer, seismometer, an ombrometer, asurveillance camera, a security gate, and the like. Thefacility/equipment information includes pieces of information fromcommunication devices installed in a school, a park, a hospital, anevacuation center, and the like.

In the social information providing system, at least the installationpositions of social infrastructure information devices andfacility/equipment information devices (to be collectively referred toas social information devices hereinafter) (information acquired by eachdevice will be referred to as social information) are registered tocollect social information acquired by each device. The collected piecesof social information are appropriately summarized and analyzed, arediscriminated according to respective information areas, are optimized,and are formed into a hierarchy, as needed. The thus generated pieces ofsocial information are extracted for each broadcast range in accordancewith needs, and distributed to each broadcast range over a broadcastwave. At this time, a user terminal apparatus can acquire part or all ofthe social information provided in the broadcast range, and acquire andbrowse, in an optimum format, the social information for each area,which changes in time series, when necessary. This allows the user tocollate position information of himself/herself and the socialinformation, and determine, based on them, the best action to be takenat the current position when, for example, emergency evacuation isrequired at the time of a disaster.

FIG. 1 is a block diagram showing the configuration of a socialinformation providing system according to this embodiment. Referring toFIG. 1, reference numeral 1 denotes a social information distributionapparatus; 2, a social infrastructure information device; 3, afacility/equipment information device; and 4, a social informationmultiplexing transmission apparatus. Each of the apparatus and deviceshas a communication function and can communicate via a network.Reference numeral 5 denotes a user terminal apparatus which exists inone of a plurality of broadcast ranges A to D classified in advance.

The social information distribution apparatus 1 includes a basicinformation registration unit 11, an information management/accumulationunit 12, an information acquisition unit 13, an information analysisunit 14, an information transmission management unit 15, a transmissioninformation generation unit 16, and information storage units 171 to 17n.

To manage various kinds of social infrastructure information devices 2and various kinds of facility/equipment information devices 3, the basicinformation registration unit 11 obtains pieces of basic informationfrom the devices, and registers them in advance in the informationmanagement/accumulation unit 12. More specifically, as the basicinformation of each of the social infrastructure information devices 2and facility/equipment information devices 3, position information of atleast a latitude and longitude (position information example: degree,minute, second, 1/100 sec, ±dd.mm,ss.sss, and the like) is saved in theinformation management/accumulation unit 12 in linkage with theidentification ID of each of the social infrastructure Informationdevices 2 and facility/equipment information devices 3. In registeringeach of the social infrastructure information devices 2 andfacility/equipment information devices 3, an identification ID which isunique in at least the system is issued and saved in the informationmanagement/accumulation unit 12 together with the position information.

The issued identification ID of each of the social infrastructureinformation devices 2 and facility/equipment information devices 3 isset in a corresponding one of the social infrastructure informationdevices 2 and facility/equipment information devices 3. Whentransmitting time-series data to the social information distributionapparatus 1, each of the social infrastructure information devices 2 andfacility/equipment information devices 3, in which the identification IDhas been set, transmits the data by adding at least the identificationID to it. The identification ID is used when connecting the socialinfrastructure information devices 2 and facility/equipment informationdevices 3 to the social information distribution apparatus 1, and ispreferably transmitted, as needed. In this system, by assuming thateach, of the social infrastructure information devices 2 andfacility/equipment information devices 3 may move, information whichdoes not change in time series, such as the identification ID of thesocial infrastructure information devices 2 and facility/equipmentinformation devices 3, classification, time-series data terms, andtime-series data attributes, are registered in addition to the basicposition (home position) of the device.

Note that it is assumed that the basic position of each of the socialinfrastructure information devices 2 and facility/equipment informationdevices 3 is changed, and thus the position information of each devicecan be updated. For example, the basic positions of an AED and a fireextinguisher which can be carried, and, mobile power supply vehicle, andthe like are preferably registered. In addition, the positions of awattmeter, power supply station sensor, thermometer, seismometer,ombrometer, surveillance camera, security gate, and the like which donot move basically are preferably registered.

In the case that a plurality of equipments are provided in a facility,assuming that one or a plurality of social infrastructure informationdevices 2 are provided in a facility, or the social infrastructureinformation devices 2 associated with a facility exist, they arehierarchically managed. In this case, at least the facility at the topof the hierarchy needs a facility/equipment identification ID. Forexample, it is preferable that in a facility designated as an emergencyevacuation center, the maximum capacity, the current evacuation state,the current number of evacuees, and evacuee information, and the likeare used as facility information (including time-series data), and asurveillance camera serving as the social infrastructure informationdevice 2 installed in the facility or a surveillance camera serving asthe nearby social infrastructure information device 2 belongs to thefacility, thereby allowing management of time-series data (real timevideo) of the surveillance camera.

Upon accepting a time-series data transmission request from each of thesocial infrastructure information devices 2 and facility/equipmentinformation devices 3, the information acquisition unit 13 at leastperforms authentication based on a social infrastructure informationdevice identification ID in the social infrastructure information device2 and performs authentication based on a facility/equipmentidentification ID in the facility/equipment information device 3,thereby accumulating time-series data in a corresponding item area ofthe information management/accumulation, unit 12. At this time,updatable items other than information of time-series data accumulatedin advance may be updated, as needed. Upon accepting the request fromthe facility/equipment information device 3, each item can be preferablyinput using a Web service or the like.

The information analysis unit 14 analyzes various kinds of socialinformation accumulated in the information management/accumulation unit12 in accordance with a designated purpose, adds an analysis result, andprocesses the accumulated information based on the analysis result,thereby accumulating resultant information in the informationmanagement/accumulation unit 12. At this time, it is preferable toaccumulate more effective analysis result, prediction information, andthe like in the information management/accumulation unit 12 by combininga plurality of data types.

The information transmission management unit 15 selects socialinformation and its items to be broadcast by referring to the pieces ofsocial information accumulated in the informationmanagement/accumulation unit 12, determines a broadcast format includingat least classification of broadcast ranges (areas), a broadcastingtime, and a repetition count within the broadcasting time whenbroadcasting the selected social information, and designates decisionsand issues a broadcast request to the transmission informationgeneration unit 16 and the social information multiplexing transmissionapparatus 4.

Upon accepting the designation and request from the informationtransmission management unit 15, the transmission information generationunit 16 extracts corresponding social information and its items from theinformation management/accumulation unit 12, performs discrimination andforms a hierarchy, as needed, generates broadcasting social informationin an appropriate format as broadcasting data, and stores the socialinformation in the information storage units 171 to 17 n for, forexample, each of the discriminated contents for broadcast ranges. Thebroadcasting data preferably has, as an appropriate format, for example,a format complying with MPEG-2 System (ITU-T H.222.0|ISO/IEC 13818-1), aformat complying with FLUTE (File Delivery over Unidirectional Transport(RFC 3926)), a format complying with the ARIB standard, or the like.

Upon accepting the designation and request from the informationtransmission management unit 15, the social information multiplexingtransmission apparatus 4 selectively acquires information necessary foreach broadcast range from the social information generated by thetransmission information generation unit 16, performs multiplexing byincluding content information such as video data and audio data, asneeded, performs discrimination and forms a hierarchy, as needed,optimizes the information as broadcasting data, and transmits theresultant data to each corresponding broadcast range. That is, thesocial information multiplexing transmission apparatus 4 multiplexes andtransmits the input information in consideration of the broadcastingtime of each piece of social information designated to be broadcast bythe information transmission management unit 15 and the repetition countwithin the broadcasting time for each piece of social information. Atthis time, the input information is preferably transmitted whileadjusting the transmission band with the content information such asvideo data and audio data. In this case, if the broadcasting time ofeach piece of social information designated by the informationtransmission management unit 15 and the repetitive count within thebroadcasting time for each piece of social information change due to thechange of the band, whether to prioritize the broadcasting time orrepetition count is preferably selected or determined in advance. Notethat a broadcast range is preferably, hierarchically determined like thewhole country A, the region B, the city, town, or village C, and thelocal area D.

The user terminal apparatus 5 is a device capable of determining thecurrent position, such as a navigation device, a smartphone and a PC,which receives at least one broadcast wave registered and set orselected by the user, extracts processable social information fromreceived data, and displays, on a display, part or all of theinformation by including the relationship between the current positionand a position indicated by the information. This allows the user toconfirm the position by referring to the displayed information, make acharging reservation, and go to the spot.

The social information acquisition unit 21 receives at least onebroadcast wave, and determines whether data transmitted by the broadcastwave includes data (a range or the like) corresponding to the selfdevice. If such data is included, the social information acquisitionunit 21 reads and grasps processing contents to be done by the selfdevice from the data of the received broadcast wave, and sends aprocessing request to the data acquisition unit 22 and the datatransmission unit 24 based, on the grasped contents.

The data acquisition unit 22 acquires time-series data (various kinds ofdetection information such as a video, audio, position information)detected by a camera, a sensor, and the like, processes the acquireddata as transmission data to the social information distributionapparatus 1, as needed, and issues the resultant data to the datatransmission unit 24. In addition, the data is accumulated in the dataaccumulation unit 23, as needed. If the social information acquired bythe social information acquisition unit 21 includes processing contentsdestined for the self device, processing such as activation processing,stop processing, and processing of acquiring corresponding data isperformed based on an instruction indicated by the processing contents.

The data transmission unit 24 acquires, from the data acquisition unit22 or the data accumulation unit 23, time-series data to be transmitted,accesses the social information distribution apparatus 1 via thecommunication line using at, least the identification ID individuallyassigned to the social infrastructure information device 2, andtransmits the time-series data to the information acquisition unit 13 ofthe social information distribution apparatus 1 after authentication.The identification ID of the social infrastructure information device 2is desirably held in the self device 2 but if it is difficult to holdthe identification ID, it may be input every time using an externalinput module or the like. The data transmission unit 2 converts the datainto a transmission format which can be broadcast, such as ISDB-T,ISDB-Tmm, ISDB-S, ISDB-TSB, ATSC, DVB-T, or DTMB, and transmits theconverted data. With this processing, it becomes unnecessary to changethe broadcast format in the processing of the social informationdistribution apparatus 1, thereby reducing the processing load.

Note that this embodiment has explained a case it which the socialinfrastructure information device 2 includes the social informationacquisition unit 21, However, a device without the social informationacquisition unit 21 is also included.

First Embodiment

A mobile power supply vehicle use information providing service will beexplained as one embodiment. In this embodiment, a mobile power supplyvehicle will be referred to as a social infrastructure informationdevice 2.

In a social information distribution apparatus 1, a basic informationregistration unit 11 acquires in advance basic information of the mobilepower supply vehicle 2, and registers the basic information, including abasic position (home), in an information management/accumulation unit12. At this time, in social information about the mobile power supplyvehicle 2, a current position, a waiting time, the number of chargeablevehicles, an estimated sold-out time, and the like are registered asdata items of the information which change in time series, and aprovider name, a car registration number, a charging type (three-phase200 V quick charging type or the like), a chargeable time (20 min or thelike), the number of vehicles simultaneously charged, a unit price, anda reservation URL (http://xxx/xxxx . . . ) are registered as data itemsof the information which do not change in time series. The mobile powersupply vehicle 2 provides the current position, the waiting time (15 minor the like), the number of chargeable vehicles (45 or the like), andthe estimated sold-out time (21:45 or the like) of the time-series datato an information acquisition unit 13 using the identification ID of themobile power supply vehicle 2 issued at the time of registration.

The information management/accumulation unit 12 accumulates the socialinformation provided from the mobile power supply vehicle 2 togetherwith an acquisition date/time.

An information analysis unit 14 acquires the social informationaccumulated in the information management/accumulation unit 12 andsocial information of an external system reserved and managed in thereservation URL, calculates the latest number of chargeable vehicles,predicts, based on the reservation trend, the time at which the numberof chargeable vehicles is reached, and updates the social informationsuch as the number of chargeable vehicles and the expected sold-out timein the information management/accumulation unit 12.

Furthermore, the sold-out time at which electricity accumulated in themobile power supply vehicle is sold out is expected based on surroundingroad conditions accumulated in the information management/accumulationunit 12 or managed by the external system.

A road congestion status is different depending on the moving route ofthe user, and an average speed is also largely different. Therefore, theinformation analysis unit 14 acquires the road conditions ofexpressways, national roads, prefectural roads, local roads to obtain anestimated combination of roads, and determines, based on a fine analysisresult as much as possible, for each road of the combination, ageographic position where the user can arrive before the estimatedsold-out time, thereby broadcasting the information by setting theposition as an geographic area. In this case, if the vehicle smoothlymoves at high speed, a broadcast in a significantly wide area ispossible.

An information transmission management unit 15 determines items to bebroadcast and a broadcast order for the social information accumulatedin the information management/accumulation unit 12, like the positioninformation, provider name, car registration number (1234 or the like),current position, waiting time (15 min or the like), charging type(three-phase 200 V quick charging type or the like), chargeable time (20min or the like), unit price (500 yen or the like), the number ofchargeable vehicles (45 or the like), the number of vehiclessimultaneously charged (5 or the like), expected sold-out time (21:45 orthe like), and reservation URL (http://xxx/xxxx . . . or the like).Based on information of the geographic area analyzed by the informationanalysis unit 14, a broadcast range (area) at the time of a broadcast isdetermined. In addition, the broadcasting time (the current time to21:40, 5-min update, and the like) and the repetition count(undesignated (as large as possible within the broadcast band/time) orthe like) within the broadcasting time are determined. The thusdetermined information is designated to a transmission informationgeneration unit 16 and, a social information multiplexing transmissionapparatus 4, thereby requesting processing.

Upon accepting the designation and request from the informationtransmission management unit 15, the transmission information generationunit 16 extracts corresponding information from the informationmanagement/accumulation unit 12, discriminates data to be transmittedbetween data for a car navigation device, data for a smartphone, datafor a PC, and the like in accordance with the types of user terminalapparatus, and converts the data into that appropriate for each userterminal apparatus to generate broadcasting data. In this embodiment,since the transmission data are at the same level and user terminalapparatuses 5 are at the same level, it is not necessary to form ahierarchy of broadcast ranges. The broadcasting data preferably has, forexample, a format complying with MPEG-2 System (ITU-T H.222.0|ISO/IEC13818-1), a format complying with FLUTE (File Delivery overUnidirectional Transport (RFC 3926)), a format complying with the ARIBstandard, or the like.

Upon accepting the designation and request from the informationtransmission management unit 15, the social information multiplexingtransmission apparatus 4 selects information necessary for eachbroadcast range from the social information generated, by thetransmission information generation unit 16, and performs multiplexingby including broadcasting data such as video data and audio data, asneeded. For each broadcast range, the social information multiplexingtransmission apparatus 4 converts the information into a broadcastformat which can be broadcast, such as ISDB-T, ISDB-Tmm, ISDB-S,ISDB-TSB, ATSC, DVB-T, or DTMB, and transmits the converted information.At, the time of transmission, during the broadcasting time of thebroadcast social information designated by the information transmissionmanagement unit 15, multiplexing and transmission are performed inconsideration of the repetition count within the broadcasting time foreach piece of social information. Note that transmission is preferablyperformed while adjusting the band with the broadcasting data such asvideo data and audio data.

In this case, if the broadcasting time of each piece of socialinformation designated by the information transmission management unit15 and the repetitive count within the broadcasting time for each pieceof social information change due to the change of the band along with anincrease in amount of transmission information in case of an emergency,whether to prioritize the broadcasting time or repetition count ispreferably selected every time or determined in advance.

The user terminal apparatuses 5 include a car navigation device,smartphone, and PC. Each user terminal apparatus 5 receives at least onebroadcast wave registered and set or selected by the user, extractsprocessable social information from received data, and displays part orall of the information. This allows the user to confirm the position byreferring to the displayed information, make a charging reservation, andgo to the spot.

This first embodiment has exemplified the mobile power supply vehicle.By accumulating various kinds of information together with the currentposition from a moving vehicle, analyzing past information to latestinformation in accordance with a use application, optimizing an analysisresult into information expected to be desired by the user, and timelytransmitting the information to a necessary area, it can be expected toimprove the convenience, and provide an appropriate guidance, therebyimproving the social efficiency. Furthermore, since the transmissionformat is a broadcast, a number of users can simultaneously useinformation regardless of restrictions on a communication line andequipment.

Second Embodiment

A charging station use information providing service will be describedaccording to the second embodiment. In this embodiment, a chargingstation will be referred to as a facility/equipment information device3.

In a social information distribution apparatus 1, a basic informationregistration unit 11 acquires in advance basic information of thecharging station 3 serving as a facility/equipment information device,and registers the basic information in an informationmanagement/accumulation unit 12 together with position information. Atthis time, in social information about the charging station 3, a waitingtime is registered as a data item of the information which changes intime series, and a provider name, business hours (24 hours or the like),a charging type (three-phase 200 V quick charging type or the like), achargeable time (20 min or the like), the number of vehiclessimultaneously charged (10 or the like), a unit price (500 yen or thelike), and a reservation URL (http://xxx/xxxx . . . ) are registered asdata items of the information which do not change in time series. Thecharging station 3 provides the waiting time (5 min or the like) of thetime-series data to an information acquisition unit 13 using theidentification ID of the charging station 3 issued at the time ofregistration.

The information management/accumulation unit 12 accumulates the socialinformation provided from the charging station 3 together with anacquisition date/time.

An information analysis unit 14 expects the sold-out time based onsurrounding road conditions accumulated in the informationmanagement/accumulation unit 12 or managed by an external system, andspecifies a geographic area where the user is expected to be able toarrive before the expected sold-out time.

If, for example, the user moves on an expressway by car from Tokyo toOsaka, he/she can grasp in advance the positions of power supplystations capable of supplying power.

An information transmission management unit 15 determines items to bebroadcast and a broadcast order from the social information accumulatedin the information management/accumulation unit 12, like the positioninformation, provider name, waiting time (5 min or the like), chargingtype (three-phase 200 V quick charging type or the like), chargeabletime (20 min or the like), unit price (500 yen or the like), the numberof vehicles simultaneously charged (10 or the like), business hours (24hours or the like), and reservation URL (http://xxx/xxxx . . . ).Especially, a broadcast range (area) within which the information is tobe broadcast is determined from a geographic area which may be used bythe user. The broadcasting time (24 hours, 5-min update, and the like)and the repetition count (undesignated (as large as possible within thebroadcast band/time)) within the broadcasting time are determined, anddesignated to a transmission information generation unit 16 and a socialinformation multiplexing transmission apparatus 4, thereby requestingprocessing.

Upon accepting the designation and request from the informationtransmission management unit 15, the transmission information generationunit 16 extracts corresponding data from the informationmanagement/accumulation unit 12. The transmission information generationunit 16 discriminates the data to be transmitted between data for a carnavigation device, data for a smartphone, data for a PC, and the like inaccordance with the types of user terminal apparatuses, and converts thedata into that appropriate for each user terminal apparatus to generatebroadcasting data. In this embodiment as well, since the transmissiondata are at the same level and the user terminal apparatuses are at thesame level, it is not necessary to form a hierarchy of broadcast ranges.The broadcasting data preferably has, for example, a format complyingwith MPEG-2 System (ITU-T H.222.0|ISO/IEC 13818-1), a format complyingwith FLUTE (File Delivery over Unidirectional Transport (RFC 3926)), aformat complying with the ARIB standard, or the like.

Upon accepting the designation and processing request from theinformation transmission management unit 15, the social informationmultiplexing transmission apparatus 4 selects information necessary foreach broadcast range from the social information generated by thetransmission information generation unit 16, and performs multiplexingby including broadcasting data such as video data and audio data, asneeded. For each broadcast range, the social information multiplexingtransmission apparatus 4 converts the information into a broadcastformat which can be broadcast, such as ISDB-T, ISDB-Tmm, ISDB-S,ISDB-TSB, ATSC, DVB-T, or DTMB, and transmits the converted information.At the time of transmission, multiplexing and transmission are performedin consideration of the broadcasting time of the broadcast socialinformation designated by the information transmission management, unit15 and the repetition count within the broadcasting time for each pieceof social information. Note that transmission is preferably performedwhile adjusting the band with the broadcasting data such as video dataand audio data. In this case, if the broadcasting time of each piece ofsocial information designated by the information transmission managementunit 15 and the repetitive count within the broadcasting time for eachpiece of social information change due to the change of the band alongwith an increase in amount of transmission information in case of anemergency, whether to prioritize the broadcasting time or repetitioncount is preferably selected every time or determined in advance.

Each user terminal apparatus 5 receives at least one broadcast waveregistered and set or selected by the user, extracts processable socialinformation from received data, and displays part or all of theinformation on a display. This allows the user to confirm the positionby referring to the displayed information, make a charging reservation,and go to the spot.

The second embodiment has exemplified the charging station. However,with respect to increasing facilities or decreasing socialinfrastructure or stores in accordance with needs in the future, variouskinds of social information are accumulated together with positioninformation and analyzed in accordance with a use application, ananalysis result is optimized to information desired by the user, and theinformation is timely transmitted to a necessary area. This allows theuser to take rational action, thereby saving the time, resources, andthe like.

In a social information distribution apparatus 1, a basic informationregistration unit 11 acquires in advance basic information of theevacuation facility 3 serving as a facility/equipment informationdevice, and registers the basic information in an informationmanagement/accumulation unit 12 together with position information. Atthis time, in social information about the evacuation facility 3, thecurrent number of evacuees, a facility operation state, evacueeinformation, the number of urgent injured people, shortage information,and the like are registered as data items of the information whichchange in time series, and a facility name (Anshin Gakuen high school orthe like) and the maximum capacity (1,200 people or the like) areregistered as data items of the information which do not change in timeseries. In addition, PCs (10 PCs/regional household information has beenregistered, or the like), AEDs (2 AEDs or the like), blankets (1,200blankets or the like), food (1,200 people/2 meals or the like),evacuation guidance devices (PC vide video guidance devices for leaders,sub-leaders, group leaders, ordinary people, and the like), and medicalsupplies (class B/2, class C/10, or the like) are also preferablyregistered as equipment information.

In addition, surveillance cameras of social infrastructure informationdevices 2 installed in the facility or surveillance cameras of nearbysocial infrastructure information devices 2 preferably belong to thefacility, thereby linking time-series data (real time videos) of thesurveillance cameras with each other. The current number of evacuees(952), a facility state (safe: partially collapsed/slightly high densityand the like), evacuee information (names/ages and the like), the numberof urgent injured people (8 or the like), and shortage information(doctor: 1, nurse: 2, guide sub-leader: 15, blanket: 52, AED battery: 2,water: 2,000 L, and the like) are distributed using the identificationID of the facility/equipment information device 3, which has been issuedby the evacuation facility at the time of registration in an informationacquisition unit 13, and accumulated in the informationmanagement/accumulation unit 12 together with an acquisition date/time.

An information analysis unit 14 preferentially, discriminates urgentinformation such as the number of injured people (8), who need to beurgently treated, from the information accumulated in the informationmanagement/accumulation unit 12 and issues the information to acooperative external system, or acquires information about whether totake measures to arrive at a solution by contact, an expected time, andconditions, and performs update in the information acquisition unit 13based on the acquired pieces of information. A geographic area which canuse the evacuation facility is specified based on the surrounding roadconditions. An information transmission management unit 15 determinesitems to be broadcast and a broadcast order from the informationaccumulated in the information management/accumulation unit 12. Thisdetermination processing is performed based on information of, forexample, the position information, maximum capacity (1,200 people), thecurrent number of evacuees (952), facility state (safe: partiallycollapsed/slightly high density), evacuee information (names/ages), andshortage information (doctor: 1, nurse: 2, guide sub-leader: 15,blanket: 52, AED battery: 2, water: 2,000 L, and the like).

The information transmission management unit 15 determines a broadcastrange (area), within which data is to be broadcast, from a geographicarea which may be used, also determines a broadcasting time (24 hours,15-min update) and a repetition count (undesignated (as large aspossible within the broadcast band/time)) within the broadcasting time,and designates the pieces of determined information to a transmissioninformation generation unit 16 and a social information multiplexingtransmission apparatus 4, thereby request to execute processing.

Upon accepting the designation and request from the informationtransmission management unit 15, the transmission information generationunit 16 extracts corresponding data from the informationmanagement/accumulation unit 12, discriminates data to be transmittedbetween data for a smartphone, data for a PC, and the like in accordancewith the types of user terminal apparatuses, and converts the data intothat appropriate for each user terminal apparatus to generatebroadcasting data. In this embodiment, as the transmission data, theevacuee information (names/ages and the like), the number of urgentinjured, people, and shortage information are preferably formed into ahierarchy to generate broadcasting data in a format corresponding to theconditions of each user terminal apparatus.

The broadcasting data preferably has, for example, a format complyingwith MPEG-2 System (ITU-T H.222.0|ISO/IEC 13818-1), a format complyingwith FLUTE (File Delivery over Unidirectional Transport (RFC 3926)), aformat complying with the ARIB standard, or the like.

Upon accepting the designation and request from the informationtransmission management unit 15, the social information multiplexingtransmission apparatus 4 selects information, necessary for eachbroadcast range from the social information generated by thetransmission information generation unit 16, and performs multiplexingby including broadcasting data of a surveillance camera in the facilityor a nearby linked surveillance camera, as needed, thereby transmittingthe information to each broadcast range. The information is convertedinto a transmission format which can be broadcast, such as ISDB-T,ISDB-Tmm, ISDB-S, ISDB-TSB, ATSC, DVB-T, or DTMB, and then transmitted.At the time of transmission, multiplexing and transmission are performedin consideration of the broadcasting time of the broadcast socialinformation designated to be broadcast by the information transmissionmanagement unit 15 and the repetition count within the broadcasting timefor each piece of social information. Note that transmission ispreferably performed while adjusting the band with the broadcasting datasuch as video data and audio data. In this case, if the broadcastingtime of each piece of social information designated by the informationtransmission management unit 15 and the repetitive count within thebroadcasting time for each piece of social information change due to thechange of the band along with an increase in amount of transmissionInformation in case of an emergency, whether to prioritize thebroadcasting time or repetition count is preferably selected every timeor determined in advance.

Each user terminal apparatus 5 receives at least one broadcast waveregistered and set or selected by the user, extracts processable socialinformation from received data, and displays part or all of theinformation. This allows the user to confirm the position by referringto the displayed information, grasps in advance information of theevacuation facility, and go to the spot. In addition, an application ispossible in which family information is set in the user terminalapparatus 5, and if a corresponding person is in the evacueeinformation, the user is notified of it. The user terminal apparatus 5can also acquire and browse the number of urgent injured people andshortage information in accordance with a user designation input oradvance condition settings.

Note that since demand for evacuation facility information in thisembodiment increases in case of an emergency, the load of acommunication line is assumed to be temporarily very high. Inconsideration of this, it is desirable to prioritize communication (inthis example, time-series information) between each evacuation facilityand a center for managing information of each evacuation facility overcommunication by general users. On the other hand, in this embodiment,since evacuation facility information is provided in a broadcast format,the general users can obtain the evacuation facility information withoutusing the communication line, and this embodiment can thus contribute toreduction in load of the communication line. Furthermore, people incharge of an emergency who are scattered and work in a wide area canquickly acquire information of each evacuation facility, and can thustake rational action, thereby saving labor, time, and the like.

Fourth Embodiment

Evacuation guidance information provision will be described as thefourth embodiment. In this embodiment, a seismometer, thermometer,rainfall and water-level telemeter, surveillance camera, disasterprevention speaker, evacuation guidance street panel, and the like willbe collectively referred to as social infrastructure information devices2.

In a social information distribution apparatus 1, a basic informationregistration unit 11 acquires in advance basic information of the socialinfrastructure information device 2 (a seismometer, thermometer,rainfall and water-level telemeter, surveillance camera, disasterprevention speaker, evacuation guidance street panel, or the like), andregisters the basic information in an informationmanagement/accumulation unit 12 together with position information ofeach device. At this time, in social information about an evacuationguidance 3, information (a seismic intensity, temperature, rainfall,water level, or surveillance video) detectable by each device and thepresence/absence of a power supply (OK, absence/battery being operating)are registered as data items of the information which change in timeseries, and a management number, acquired data classification, theoperating time by the battery, and the like are registered as data itemsof the information which do not change in time series. Basic informationof the facility/equipment information device 3 in the evacuation area isacquired, and registered together with position information. The datawhich change in time series and the data which do not change in timeseries may be registered as in the third embodiment. However, in thecase of a facility such as a park, only minimum information (anevacuation area name, currently safe, about 600 evacuees, and the like)may be registered. Pieces of information from various socialinfrastructure information devices 2 and various facility/equipmentinformation devices 3 are accumulated in the informationmanagement/accumulation unit 12 together with an acquisition date/time.

An information analysis unit 14 analyzes the properties of theevacuation guidance from the information accumulated in the informationmanagement/accumulation unit 12, and further acquires necessaryinformation of an external system in accordance with the properties. Forexample, when a tsunami will occur, compound information such as anestimated height, estimated arrival time, temperature sensor,surveillance camera video, reported fire, and roadpassability/impassability information is acquired and analyzed tospecify an optimum guidance route to an evacuation area corresponding toa user position, thereby accumulating it in the informationmanagement/accumulation unit 12.

An information transmission management unit 15 determines items to bebroadcast and a broadcast order from the information accumulated in theinformation management/accumulation unit 12, like the positioninformation, evacuation area name, and guidance route. In addition, abroadcast range (area) within which information is to be broadcast isdetermined from a geographic area which may be used. A broadcasting time(24 hours, 1-min update, and the like) and a repetition count(undesignated (as large as possible within the broadcast band/time))within the broadcasting time are determined, and the determined contentsare designated to a transmission information generation unit 16 and asocial information multiplexing transmission apparatus 4, therebyrequesting execution.

Upon accepting the designation and request from the informationtransmission management unit 15, the transmission information generationunit 16 extracts corresponding data from the informationmanagement/accumulation unit 12, discriminates the data to betransmitted between data for a social information device, data for a carnavigation device, data for a smartphone, data for a PC, and the like inaccordance with the types of user terminal apparatuses, and converts thedata into that appropriate for each user terminal apparatus to generatebroadcasting data.

The broadcasting data preferably has, for example, a format complyingwith MPEG-2 System (ITU-T H.222.0|ISO/IEC 13818-1), a format complyingwith FLUTE (File Delivery over Unidirectional Transport (RFC 3926)), aformat complying with the ARIB standard, or the like.

Upon accepting the designation and request from the informationtransmission management unit 15, the social information multiplexingtransmission apparatus 4 selects information necessary for eachbroadcast range from the social information generated by thetransmission information generation unit 16, and performs multiplexingby including broadcasting data of a surveillance camera in a facility ora nearby linked surveillance camera, as needed, thereby transmitting theinformation to each broadcast range. The information is converted into atransmission format which can be broadcast, such as ISDB-T, ISDB-Tmm,ISDB-S, ISDB-TSB, ATSC, DVB-T, or DTMB, and then transmitted. At thetime of transmission, multiplexing and transmission are performed inconsideration of the broadcasting time of the broadcast socialinformation designated by the information transmission management unit15 and the repetition count within the broadcasting time for each pieceof social information. Note that transmission is preferably performedwhile adjusting the band with the broadcasting data such as video dataand audio data. In this case, if the broadcasting time of each piece ofsocial information designated by the information transmission managementunit 15 and the repetitive count within the broadcasting time for eachpiece of social information change due to the change of the band alongwith an increase in amount of transmission information in case of anemergency, whether to prioritize the broadcasting time or repetitioncount is preferably selected every time or determined in advance.

Each of the disaster prevention speaker and the evacuation guidancestreet panel desirably receives a broadcast wave from the distributionapparatus 1, and acquires evacuation, guidance information correspondingto an installation position to provide an optimum guidance. Each userterminal apparatus 5 receives at least one broadcast wave registered andset or selected by the user, extracts processable social informationfrom received data, and displays part or all of the information on adisplay. This allows the user to evacuate in accordance with theevacuation guidance information displayed on the display. Furthermore,the user can determine an evacuation route in the field using the userterminal apparatus 5 based on the current position and the guidanceinformation provided by the broadcast wave.

This embodiment has exemplified an evacuation guidance based on a resultof analyzing compound time-series information and the like based onvarious social information devices. A social information device fortransmitting information to evacuees, such as a disaster preventionspeaker or evacuation guidance street panel, can provide an optimumevacuation guidance in its location by receiving social informationprovided over a broadcast wave. Even a general user who does not know anevacuation area can readily know it. A general user who knows anevacuation area can arrive at the evacuation area by avoiding a routewhich he/she must not go. As described above, the user can save labor,time, and the like, thereby improving safety in terms of variousaspects.

It is possible to more appropriately provide an evacuation guidance byappropriately selecting division of broadcast ranges. For example,assuming that an earthquake has occurred in Tokyo Bay, compoundinformation such as time-series data from the social infrastructureinformation devices 2 and facility/equipment information devices 3installed in respective locations and information of an external system,are acquired, the contents are discriminated for each broadcast range totransmit an optimum guidance route to an evacuation area correspondingto a user position. FIG. 5 shows an example. Referring to FIG. 5, abroadcast range A indicates the whole of Japan; a broadcast range B, anentire area along the sea in the Kanto area; a broadcast range C, anarea around Tokyo Bay; and broadcast ranges D, an area on the bay sideof Koto Ward, an area on the bay side of Minato Ward, and an area on thebay side of Ota Ward, respectively.

In the above example, the height of a tsunami of 10 m, an expectedarrival time of 10:22, an effective evacuation area information(including position information) for each position information area(obtained by subdividing a broadcast range in accordance with a userposition), and evacuation information of an optimum evacuation route aretransmitted to user terminal apparatuses the small area on the bay sideof Ota Ward, and evacuation information for a disaster preventionspeaker and an evacuation guidance street panel for each positioninformation area (obtained by subdividing the broadcast range inaccordance with the user position) is also transmitted. In Minato Wardand Koto Ward as well, evacuation information corresponding to abroadcast range is transmitted. The user can receive a broadcast in thesmall area using a user terminal apparatus, and acquire information froma disaster prevention speaker and evacuation guidance street panel,thereby optimally evacuating by avoiding a risk and congestion timelyand practically.

In a broadcast in the whole area of Tokyo Bay, ship guidanceinformation, vehicle guidance road information, and the like areeffective in addition to the height and expected arrival time of atsunami. As these pieces of information, information for each socialinformation device linked with the identification ID of the socialinfrastructure information device 2 is transmitted. For example, in thecase of a disaster prevention speaker, audio information suitable for aninstallation location is transmitted, or a plurality of pieces of audioinformation are accumulated in advance on the disaster preventionspeaker side and information for selecting and instructing one piece ofaudio information to be output from the disaster prevention speaker istransmitted. Similarly, as for the evacuation guidance street panel,video information suitable for an installation location is transmitted,or a plurality of pieces of video information may be accumulated inadvance on the street panel side and information for selecting andinstructing one piece of video information to be displayed on theevacuation guidance street panel may be transmitted.

In a broadcast in the whole area along the sea in the Kanto area, aseismic intensity and aftershock predication information of each area,transportation operation information of trains and the like,evacuation/safety information and, if necessary, evacuation necessityinformation for each position information area (obtained by subdividinga broadcast range in accordance with a user position), evacuationfacility information, and evacuee information as well as information foreach social information device linked with the identification ID of thesocial information device are transmitted. In addition, rescue contents,position information, necessary equipment, and the like are preferablytransmitted as information for rescuers.

In a broadcast in the whole country, information for each socialinformation device linked with the identification ID of the socialinformation device such as evacuation/safe information is transmitted inaddition to a seismic intensity and aftershock predication informationof each area, road information, and transportation operation informationof trains, planes, and the like. Rescue contents, position information,necessary equipment, and the like are preferably transmitted asinformation for rescuers outside a disaster-stricken area. As describedabove, by classifying and broadcasting optimum information at this pointof time in each range, the user can quickly take timely action at anyposition, thereby improving the efficiency of an evacuation guidance.

If an emergency transmission request like emergency evacuationinformation is received, an emergency data rate is ensured, and then anormal data rate is calculated based on the entire usable communicationband, thereby changing the normal data rate in accordance with theinformation amount of emergency information, as shown in FIG. 6. Theband control for information is performed by weighting information to betransmitted. Assume that the amount of emergency information is large.In this case, if normal information transmission is suddenly limited,the user may become confused, and thus the normal data rate is graduallylimited in accordance with the information amount.
